    • One embodiment of a method for calibrating a test color measurement device in conjunction with an emissive display includes measuring initial spectral sensitivities of at least four channels of the test color measurement device, linearly regressing the spectral sensitivities to a least-square best fit to CIE color matching functions, measuring CIE tristimulus values of test colors on the display using a reference color measurement device, measuring the CIE tristimulus values on the display using the test color measurement device, transforming the CIE tristimulus values measured by the test color measurement device to CIE tristimulus values that would have been measured by the reference color measurement device, using a nonlinear function with variable fitting coefficients, and storing initial fitting coefficient values that provide a least-square best fit of the CIE tristimulus values measured by the test color measurement device and the CIE tristimulus values measured by the reference color measurement device.
